The hex color #0A2533, also known as Firefly, presents accessibility challenges due to its dark nature. When used as a background color, it necessitates very light text (ideally white or a near-white shade) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Firefly may struggle to meet these ratios with many common text colors. Therefore, careful consideration and testing with accessibility evaluation tools are essential. Designers should check contrast ratios using online tools or browser extensions. Providing alternative color schemes with higher contrast is also a good practice. For users with visual impairments, poor contrast can render content unreadable, hindering their ability to access information effectively. Avoid pairing it with dark grays or blues.
